NIS server Vulnerability Scan
Vulnerability Scan Summary
Checks the presence of a RPC service
Detailed Explanation for this Vulnerability Test
The remote host is a NIS server. NIS is used to share password files among
the hosts of a given network, which must not be intercepted by a possible hacker.
Usually, the first step of their attack is to acertain whether they are
attacking a NIS server, which make the host a more valuable target.
Since we could acertain that the remote host is a NIS server, they can
acertain too, which is not a good thing.
Solution : filter incoming TCP and UDP traffic to prevent them from connecting
to the portmapper and to the NIS server.
Threat Level: Low
